The side frame comprises an extrusion (118) which defines a slot (131) and through holes (117,127). A fitting (140) is secured to the end of the strut (160) and includes arms (142,144) which define through holes (142,145) to accommodate the pin (146).

Description: This invention relates to an arrangement of a boat canopy and a windshield assembly, and more particularly provides an arrangement in which means are provided for rapidly attaching and detaching an end of a strut forming part of the canopy to a side frame of the windshield assembly. A variety of techniques have been described in the prior art for attaching a canopy or similar cover to a fixed structure, such as a boat windshield. Typically, metal fastening systems are utilized along the edge of the fixed structure, with mating fasteners on the cover. Examples of such arrangements are shown in the following United States patents: 4,750,449 to Muhlberger; 2,961,725 to McGhie; 2,937,652 to Zimmer et al.; 3,416,282 to Daugherty; 3,093,845 to Brock et al.; 2,961,725 to McGee; 3,021,535 to Dorst; 3,930,738 to Thuss et al.; and 4,993,351 to Zirkelbach et al. Canadian Patent 685,026 is also of interest. WO 90/08068 discloses an arrangement of a hood frame and a windscreen assembly in which a base frame of the hood frame comprises an extruded profile having slots therein in which a bead formed around the edge of the hood engages to secure the hood to the extrusion. Fastening means are also provided on the extruded profile having heads which engage in slots formed in struts of the hood frame to fasten the hood frame to the vessel. The present invention provides an improvement in arrangements of a boat canopy and a windshield assembly by providing means for rapidly attaching and detaching an end of a strut which, in use, supports the cover material of the canopy, to a side frame of the windshield assembly. According to one aspect of the present invention there is provided an arrangement of a boat canopy and a windshield assembly, comprising a boat canopy including a cover of flexible material and at least one strut for supporting the cover in a use configuration, and a windshield assembly including a side frame having an extrusion across the top thereof, characterised by a lateral hole provided in the extrusion, a fitting member which is attached to a joint member carried on the strut and which has holes extending therethrough, and a quick release pin which, in use, releasably engages through said holds of said fitting member and said lateral hole so as to rapidly secure the fitting member to the extrusion. Various detailed features of the fitting and pin lead to particular advantageous embodiments of the invention. The invention also provides a method for rapidly attaching and detaching a boat canopy and windshield assembly comprising the steps of: providing an extrusion member attached along the top of a side frame of the boat windshield assembly, said extrusion member having a lateral hole; providing a fitting member which is attached to a joint member carried on a strut of the boat canopy and which has holes extending therethrough; engaging said fitting member on said extrusion member so that said lateral hole of the extrusion member aligns with the holes of the fitting member, and inserting a locking pin through said holes in said fittingmember and said lateral hole of the extrusion so as rapidly to attach the fitting member to the extrusion member. In preferred embodiments of the invention, the flexible material of the cover is secured to the windshield assembly along part of the periphery of the cover by a flexible member which cooperates with a slot provided at the upper edge of the windshield assembly. The above and further features and advantages of the invention will become clear from the following description of a preferred embodiment thereof, given by way of example only, reference being had to the accompanying drawings wherein: Figure 1 is a cross section of a boat canopy and windshield assembly; Figure 2 is a cross section like that of Figure 1 showing an intermediate stage in the locking operation; Figure 3 is a cross section like that of Figures 1 and 2 illustrating the boat canopy and windshield assembly in a locking configuration; Figure 4 is a cross sectional view like that of Figures 1 - 3 illustrating a step in the unlocking of the flexible member associated with the boat canopy from the gripping member of the boat windshield; Figure 5 is a top plan view of the flexible member attached to the inside surface of a boat canopy; Figure 6 is an end view of the arrangement shown in Figure 4, during the unlocking operation, with various elements partially cut away; Figure 7 is a perspective view of a system in accordance with the present invention for rapidly attaching a boat canopy to a boat windshield assembly, as viewed from the passenger area of an associated boat; Figure 8 is a cross sectional elevation of a side frame attachment portion of the system illustrated in Figure 7; and Figure 9 is a perspective view of the side frame portions of the attachment system shown in Figures 7 and 8, as viewed from the outside of the associated boat A preferred embodiment of the present invention will now be described with reference to the drawings. Reference is first made to Figure 1 where a boat windshield and canopy assembly, referred to generally by the reference numeral 10, is shown. In Figure 1 the assembly 10 includes a boat windshield 12 having an upper extremity 13 and a boat canopy 14 having an inside surface 15. As illustrated, there is provided a gripping member 16 formed of an extrusion of a suitable material, for example aluminum, having a pair of arms 18, 20 and an internal plate 24 adapted to fit across the upper extremity 13 of the boat windshield 12, and along its sides, as shown. Suitably, a gasket material 22 is inserted between the gripping member 16 and the boat windshield 12. The extrusion 16 includes an internal plate 26 extending from plate 24 to curved plate 28 defining the upper extremity of the gripping member 16. The radius of the upper plate 28 is not critical, but is intended to provide a rounded surface for the boat canopy 14, and its associated flexible member which is described in greater detail below. With continued referenced to Figure 1, the gripping member 16 includes an internal recess 30 communicating with a slot 31, which slot extends generally parallel with the boat windshield. The slot 31 is defined by the extremities of the arm 18 and the upward radial plate 28. The internal recess 30 is defined by a tapered surface 32. The flexible member 40 is defined by a flat plate 41, a first portion, or riser 44 extending laterally from the plate 40 and first and second locking segments 46 and 50 which extend, respectively, in forward and rearward directions with respect to the peripheral edge 36 of the canopy 14 in the embodiment of Figures 1-4. The plate 40, the riser 44 and the first and second locking segments 46, 50 comprise an integrally molded flexible member which is attached to the inside surface 15 of the canopy 14 by threads 42, adjacent the rolled periphery 36 of the canopy 14. As is shown in Figure 1, the second locking segment 46 has an inside tapered surface 48 generally conforming to the taper of the surface 32 along the internal recess 30 of the gripping member 16. As is further shown in Figure 1, the forward locking segment 50 is substantially thinner in cross sectional dimension than the rearward locking segment 46, to thereby impart greater flexibility to that forward locking segment. The configuration of the flexible member, including its plate 41, the first, riser portion 44 and the rearward and forward locking tabs 46, 50, respectively, when reference is made to the plan view of Figure 5. Referring again to Figure 1, the flexible member 40 is locked into the gripping member 16 by first drawing the peripheral edge 36 of the boat canopy 14 downwardly and generally parallel to the boat windshield 12 as is shown by the arrow A in Figure 1. Thereafter, the rearward locking segment 46 of the flexible member 40 is pushed through the slot 31 and across the tapered surface 32 of the internal recess 30 as is shown by the arrow B in Figure 1. After these two steps are accomplished, a portion of the flexible member is within the internal recess 30 of the gripping member 16, as is illustrated in Figure 2. The locking procedure is completed in the manner shown in Figure 2, by pushing the flexible member 40 downwardly as shown by arrow C in Figure 2, to drive the flexible, forward locking segment 50 across the tab 34 and into the internal recess 30. The resulting configuration is shown in Figure 3, the details of which are described next. As is shown in Figure 3, the inside tapered surface 48 of the rearward locking segment 46 lies across the corresponding tapered surface 32 of the gripping member 16 (reference numerals 48 and 32 are omitted in Figure 3, for clarity, but are set out in Figure 1). As will be appreciated by those skilled in the art, the canopy 14 has a significant stretch, thereby keeping the riser portion 44 of the flexible member 40 against the rear edge of the slot 31 as defined by the plate 28. In this configuration, the forward locking segment 50 is maintained in a relationship with tab 34 to just be engaged with that tab, and is not held substantially underneath that tab, as is shown in Figure 3. Such locking as between the tab 34 and the locking segment 50 is unnecessary, because of the tension of the canopy 14, and the configured locking arrangement between the tapered surfaces of the rearward locking segment 46 and the gripping member 16. Reference is now made to Figure 4. When it is desired to unlock the flexible member 40 from the gripping member 16, the peripheral edge 36 of the canopy 14 is pulled upwardly in a direction away from the arm 18, as is shown by arrow D. As this is undertaken, the forward locking segment 50 easily moves across the extremity of the tab 34. Reference is now made to Figure 6. As is shown, the forward locking segment 50 develops a rolled portion 51 as it unlocks from the tab 34. Again, this is achieved because the forward locking segment is both substantially flexible in relation to the rearward locking segment 46, and because the forward locking segment does not extend substantially underneath the tab 34 of the gripping member 16. The system and method of the present invention also contemplates a facile technique for rapidly connecting and disconnecting the boat canopy to a side frame of the windshield, as will now be described with reference to Figures 7, 8 and 9. Noting Figure 7, the boat windshield includes a side frame 110, to which the boat canopy is to be rapidly attachable and detachable. Conventionally, the boat canopy includes struts 160, 164, with the second strut 164 being attached to the first strut 160 via a plastic fitting 162. The first strut 160 is then attached to the side frame 110 utilizing a rapid attach-detach system described in detail with reference to Figure 8. The side frame 110 of the windshield comprises an extrusion 116 having various features which are substantially identical to the gripping member 16 described in Figures 1 and 2 above, and which is fitted to the top of the glass forming the side window of the windshield system. In Figure 8, the extrusion 110 has a pair of arms 18, 20 and an internal plate 124 adapted to fit across the upper extremity of the side windshield with a suitable gasket material therebetween (not shown). The extrusion 110 includes an internal plate 126 extending from the plate 124 to a curved plate 128 defining the upper extremity of the extrusion 110. The radius of the upper plate 128 is not critical, but is intended to provide a rounded surface 129. The extrusion 110 includes an internal recess 130 communicating with a slot 131, the slot extending generally parallel with the side window. The extrusion 110 differs from the gripping member 16 of Figures 1 and 2, in that there is provided two additional holes 117, 127 extending through the vertical plates 120, 126 respectively, in order to receive a detent pin 146. The detent pin 146 includes a detent ball 148 at one end, and a pull ring 150, and operates in a conventional manner to extend through the holes 131, 127 and 117. In order to rapidly attach and detach the first strut 160 to the side frame extrusion 110, there is provided a plastic fitting 140 having a pair of arms 142, 144 and an internal cavity defining a curved radius 143 that is dimensioned to face against curved surface 129. The arm 142 is provided with a hole 143, and arm 144 is provided with a slot hole 145, and with the arms dimensioned such that the holes align with the holes 131, 127 and 117 when the fitting 140 is attached over the side frame extrusion 110, as shown in Figure 8. In this manner, the detent pin 146 holds the plastic fitting 140 and the extrusion 110 together, until the detent pin 146 is removed by pulling the rings 150 to overcome the detent ball 148. The fitting 140 includes a slot 152 and a lateral hole 154 extending across the slot 152, and is dimensioned to receive the tongue 157 of a joint member 156, which is preferably plastic and has an internal portion extending into the cylindrical cavity of the first strut 160. A fastener 158, 159 extends across the lateral hole 154 and rotatably attaches the joint member 156 with the fitting 140. It will be appreciated by those skilled in the art that the strut system of the boat canopy is also provided with a similar quick attach-detach system on the opposite side of the boat, and may include similar attach-detach fittings at the stern of the boat as well. In this manner, the struts, including struts 160, 164, of the boat canopy may be rapidly attached and then later rapidly detached from the windshield and side frame assemblies. The system, apparatus and method of the present invention thus provides a mechanism for rapidly attaching a canopy or cover to a boat windshield and frame, and which is suitable for use in adverse environmental circumstances.
